Core tip: [news] many friends and users often see that titanium dioxide is used in the goods, but they can't accurately say the type of titanium dioxide It's not clear about the specific situation Now I'd like to brief you on titanium dioxide: Scientific name and type of titanium dioxide The scientific name of titanium dioxide is titanium dioxide pigment white 6 It has rutile and anatase crystal forms The whiteness of type a titanium dioxide is better, but the coloring power is only 70% of that of type R in terms of weather resistance, the addition of type a titanium dioxide test piece is only Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Home of coatings news: [news] many friends and users often see that titanium dioxide is used for goods, but they can't accurately say the type of titanium dioxide It's not clear about the specific situation Now let's briefly introduce titanium dioxide to you: the scientific name and type of titanium dioxide is titanium dioxide pigment 6 It has rutile and anatase crystal forms The whiteness of type a titanium dioxide is better, but its coloring power is only 70% of that of type R in terms of weather resistance, the test piece of type a titanium dioxide starts to crack or flake after only one year, while the appearance of type R titanium dioxide test piece only changes a little after ten years Because R-type titanium dioxide has better colouring power and weather resistance, R-type titanium dioxide is better for plastic colouring According to the manufacturing process of titanium dioxide, there are sulfuric acid method and chlorination method, both of which can produce titanium dioxide of type A and r The sulfuric acid process started in 1931, and the chlorination process started to produce type A from DuPont company in 1975 In the chlorination process, the oxidation step controls the particle size distribution and crystal structure, so that it can produce titanium dioxide with high hiding power, bottom color blue and high coloring strength Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
